sonneteer alabaster v nait 5

I ‘m in the market for a sub £1000 amp. I recently tried a Sonneteer Alabaster integrated against a Naim Nait 5, and an Audio Analogue Puccini. The AA was instantly dismissed – slow and frankly odd sounding, but to my the surprise, the Sonneteer outPRaTed the Naim by some margin – livelier, bouncier, and altogether more fun. Has anyone had any longer term experience with these amps?
